![]() Temperature Requirements: Operate equally well in any reasonable temperature condition.They have shorter service life than other light sources. Incandescent sources are expected to have a lamp life of about 1000 hours.They deliver more heat than light which results in a large quantity of wasted electricity.The larger the source, the more inefficient it is to gather up the light and drive it out in a specific direction through optical control.Instant-on/off: filaments heat up very rapidly.Dimming: Can be dimmed simply by lowering the amperage (quantity) of electricity.Ballast and Transformer: Do not require ballast and transformer.Color Temperature: Warm color appearance with low color temperature.They have short lamp life and are inefficient.

Table courtesy of Energy Rating Your Lighting Specialists across Melbourne Typical omnidirectional light bulb and price The following table sets out how the different light bulbs compare to each other. Comparing all the different light bulb types It usually costs around $5 a year to run a quality LED light in a high-traffic area of your home. The levels of heat this process generates are very low, so very little electricity gets wasted. This then makes them move around quickly through the solid material, which produces light. They send an electric charge through solid material, as opposed to filament or vapour, which engages the electrons inside. LED lights work differently from the above, which is what makes them more energy efficient. The UV then hits a phosphor lining inside the tube, which excites the phosphor and creates light that we can see. The vapour gets excited by the charge and creates invisible ultraviolet (UV) light. Fluorescent lightsīoth CFL and fluorescent tubes work in the same way - by generating an electric charge inside a glass tube filled with mercury vapour. ![]() Halogen gas speeds up the heating process, meaning the bulb can get brighter using less electricity and lasts longer (as the gas protects the filament). ![]() ![]() Halogen light bulbsĪ halogen light bulb lights up in the same way as an incandescent one does - through the heating up of the tungsten filament - however, a halogen bulb also contains halogen gas. However, the more energy used the more heat that is produced. The more energy, or watts that run through the tungsten filament, the more light (lumens) is produced. Incandescent light bulbs create light by heating a wire, known as the tungsten filament to a high temperature by running an electric current through it until it glows brightly. One thing remains the same though - a bulb that produces more heat for the same light output is simply less efficient. This may seem like a simple question, but the answer depends on the type of light bulb, as each works slightly differently than another.
